I would put forth that the diff fluid, while it may be needing to be changed due to heat/age/wear and detergents decaying over time, the metal filings on the drain plug aren't a sign of the fluid needing to be changed, but merely a sign of the diff magnet doing it's job.
Maybe I'm misinterpreting what I've read but that's the impression I get.

That may be part of it but if I recall this thread, I think the stories of black stinky goo coming out of the diff is what prompted people to change it.
I did mine while I was putting on my F.I. exhaust just because it was easier with the exhaust off.
